The 2012 outbreak that killed 76 people and sickened hundreds of others was traced to contaminated steroid injections made by the now-closed New England Compounding Center. Chin ran the clean rooms where the drugs were made.

Chin’s attorneys have tried to place the blame on the pharmacy’s co-founder, Barry Cadden.

Cadden was sentenced in June to nine years in prison after being acquitted of second-degree murder charges but convicted on conspiracy and fraud charges.
